2000 SAAB 9-3 air conditioning

76 Instruments and controlsManual climate-control
systemThe air is drawn in through an intake at the
bottom edge of the windshield. It passes
through an efficient filter before being
routed through the climate-control system
and into the cabin. The cabin discharge vent
is located on the right behind the rear
bumper. The air discharge vents should be
kept free of snow and ice in the winter.
The rate of air flow inside the car is con-
trolled by means of the fan switch. Temperature control The temperature of the incoming air can
be steplessly varied using the temperature
control.
Air distribution The air distribution control is used to direct
the flow of air to the defroster, dash and floor
vents.
The control permits settings intermediately
between the three main settings so that the
available air can be apportioned between
the floor and the windshield (defroster) or
between the floor and the panel.
To counter cold drafts from the front side
windows when the control has been set to
defroster or floor, a small flow of air issues
from the dash vents. The dash vents swivel universally, so that
the air can be directed as desired.
The flow of air through the dash vents can
be adjusted for each vent by means of the
adjacent control.
Air to the rear side windows is supplied by
the floor ducts. To demist these windows
you should therefore select a defroster/floor
combination.
If the windows are thoroughly cleaned it is
much easier to keep them free of mist.

78 Instruments and controls
The air conditioning is combined with the
conventional climate-control system and is
switched on by pressing the button,
provided that the fan control is in
position 1-4.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled and, finally, if required,
heated.
The air conditioning can be used at outdoor
temperatures down to 32°F (0°C). Condensation water When the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form. When the button is depressed the
regular air intake will be closed. In this posi-
tion, the air inside the cabin is recirculated.
Use recirculation when you want rapid cool-
ing, at extremely high air temperatures.
Switch the air conditioning (A/C) on first.
Recirculation can be useful to activate man-
ually to prevent unpleasant smells being
drawn into the car from outside.
Note that recirculation should not be
used when the outside temperature is
lower than 50°F (+10°C) except briefly,
e.g. to avoid unpleasant air from enter-
ing the car. Prolonged use of recircula-
tion could cause the windows to mist or
ice up.

82 Instruments and controlsFunctions The function you have manually selected will be locked in, while
other functions remain automatic.
Temperature maintenance, except in positions HI and LO, is, there-
fore always automatic. The active function is shown in the display.
A manual selection is cancelled by pressing AUTO or by repeated
pressing of the button used to make the manual choice. For further
functions, see ”Programming II”, page 87.
Button Display
When the system is set to AUTO, the
temperature, air distribution, fan
speed and recirculation will be con-
trolled automatically.
The air conditioning is activated auto-
matically if the outside temperature is
above 32°F (0°C). When AUTO is
depressed again, all automatically
selected settings are shown on the
display.

2 Set the desired cabin tempera-
ture using the two buttons.
3 The temperature you have now
chosen will be stored, remaining
in the memory even when the
ignition is switched off, unless
ACC has been programmed with
a different "ON" setting. See pro-
gramming, page 86.

(A/C system)
Fault diagnosis If a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked by an authorized Saab
dealer.Important!

When the A/C system is in operation, mois-
ture from the air will condense on the evap-
orator. When the car is then parked, this
condensation will drip off the evaporator
and form a small pool of water on the
ground. This is normal. The warmer the
ambient air and the higher the humidity, the
greater the amount of condensation formed.Inadequate cooling:
a Make sure that the temperature and
air-distribution controls are in the
appropriate settings, see page 77.
b Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
c Make sure that the drive belt for the com-
pressor is not slipping, see page 179.
d Check the fuses for the ventilation fans
and compressor, see page 189.
NOTE The A/C system is designed for use
with R134a refrigerant.
 Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
 All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
 Never mix R134a and R12 refriger-
ants.
WARNING
 The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
 Escaping refrigerant gas can cause
blindness or other injury.
